MOBILE, Alabama -- Former prosecutor Steve Giardini talked to an undercover FBI agent posing as a 15-year-old over the phone about improving her math grades, her pet dog, her sexual past and his desire to meet her one day, according to recordings being played in court today.

He told the girl that when she turns 16, he will take her to the beach.

"I mean no funny business," he adds. "I'm old enough to be your father."

Giardini, 51, is on trial on charges of enticing a child for sex and soliciting the production of child pornography. He worked in the Mobile County District Attorney's Office for nearly 20 years, including prosecuting sex crimes for the Child Advocacy Center. He resigned in 2009.

Prosecutors in court are continuing to play recordings of Giardini's phone conversations with the undercover agent, who used voice-altering technology to make himself sound like a young girl.

He posed as "Diana Gautier" from Daphne and met Giardini online. They later began talking on the phone.

At one point, Giardini talked to the agent about his work.

"I've been in trial a whole bunch," he says.

"I forgot, you're a lawyer right?" says the agent. "Oh, cool."

"I put really bad people in prison," Giardini adds later.

Prosecutors said in opening statements that Giardini eventually asks the girl to masturbate and arranges a meeting for a trip to the beach.

Giardini is accused of carrying on the relationship from December 2008 until April 2009.

The prosecution is continuing to play recordings for the 8-man, 6-woman jury.

The defense argues that while Giardini shouldn't have been having such conversations, his actions didn't violate state law.
